Public Meeting on Oklo Topical Reports September 16, 2021
MCA and Performance-based Licensing Topical Reports Why are they important?
- Articulate the methodologies used by Oklo in developing the licensing basis for its reactor designs
- Offer an alternative licensing approach to the current approaches being considered for Part 53
- Represent a technology-inclusive, risk-informed performance-based licensing methodology, available for use by any advanced reactor developer, to enable broader deployment as directed by NEIMA
MCA and Performance-based Licensing Topical Reports What do they do?
- Focus on the requirements for assuring adequate protection, rather than regulatory guidance developed for other technologies
- Utilize iterative processes to simplify the design, with preferential use of inherent features and passive systems over complex, active systems
- Clearly demonstrate safety significant functions and features of the design and how to apply the necessary controls to ensure their reliability
MCA and Performance-based Licensing Topical Reports Current status?
- Oklo submitted both topical reports to the NRC on 7/2/2021
- NRC staff performed completeness review and identified supplemental information to support review of both topical reports
- Oklo/NRC discussion through public meetings on the identified supplemental information and proposed resolution of NRC staff comments
MCA and Performance-based Licensing Topical Reports
- Expand scope of the topical reports to clarify applicable requirements the methodology is addressing (MCA Comment I and PB Comment I)
- What each report does.
- What each report doesnt do (PDC development - Comment I.E)
Maximum Credible Accident Topical Report
- Supplement with language to include examples of previously determined acceptable approaches based on approved guidance (MCA Comment II)
MCA and Performance-based Licensing Topical Reports
- Add new section Interfaces (MCA Comment I, III, PB Comment I)
- Explains how the topical report interfaces with other licensing approaches (licensing basis event selection, performance-based licensing, etc)
- Seeking additional clarification on MCA Comment III III. The MCA TR does not Identify the techniques for providing margin to address uncertainties associated with the performance of new and novel features in identifying initiating events/hazards/event sequences. Providing margin to account for uncertainties was identified as a common element among all the approaches for identifying hazards, initiating events, and accident scenarios (see Note 1 and Note 2).
